ABSTRACT:
Water-soluble, high molecular weight, linear copolymers of a diallyl ammonium monomer and an acrylamide monomer of various cationicities are prepared by copolymerization of a major portion of the acrylamide monomer via stage-addition in a solvent solution and adding a chain transfer agent at the conclusion of said copolymerization to prevent branching and cross-linking from occurring.
